Hey Lynn,
Sorry to hear you're struggling with this. I have dizziness problems that aren't related to anything with my ears. I spent over a year seeing specialists and they couldn't find anything either. So my rheumy, family doc and neurologist have chalked it up to my fibro and lupus. I know that when I'm flaring slightly, the dizziness gets bad. Like Chaya, it's my warning sign to slow down. I'm overdoing it.
October was a rough month for the dizzies. I had a lupus and a fibro flare all month. When those cleared up, the dizziness went away.
I hope you get the answers you need. It's awful living with it.
Ginny
